latent image

[′lāt·ənt ′im·ij]
(graphic arts)
An invisible image produced by the physical or chemical effects of light on the individual crystals (usually silver halide) of photographic emulsions; the development process makes the image visible, in the negative.

latent image

An invisible image typically of electrical charges. For example, in a copy machine, a latent image of the page to be copied is created on a plate or drum as an electrical charge.

Ironically, an early (circa 1987) integrated CR system for chest imaging, the Konica Direct Digitizer (KDD), incorporated a linear scanning mechanism (rather than advancing the PSP imaging plate) and used a special PSP material that had an extremely short luminescence rate and concomitant rapid spontaneous fading of the latent image.
Its expanded latitude and linearity provides superior highlights and shadows in a film stock with exceptional latent image stability.
Silvestri, who has 52 patents, specializes in photoreceptors, the material on which the latent image is formed prior to developing the printed image.
Cross Match also developed a Guardian based multi-modal Jumpkit, that includes all the functionality of its original military Jumpkit products, including fingerprint image capture, latent image capture, facial image capture, document scanning, voice recording, iris capture, and GPS recording, with the ability to run off an integral military battery.
Unlike their analog predecessors, digital MFPs -- those that copy, print, fax and scan -- pose an 'information security' dilemma since each page that is scanned through the MFP's document feeder results in a latent image on the system's internal hard disk drive.
Following job completion, a red alert security breach can occur when latent image data remains on the hard disk.
Submitted fingerprints are automatically queried against a latent image database, which has resulted in several new arrests.
This fingerprint biometric technology utilizes a finger's electrical field to sense a live finger, making it impossible to use a replica of a fingerprint or a latent image left on the sensor to authenticate a user.
Contrary to electrophotography with its typical laser or LED-array exposure of photoconductor drums, Nipson's magnetography technology utilizes a state-of-the-art silicon magnetographic imaging head to record a latent image on a revolving hard metal drum.
